You may continue with unrelated safe work or a genuinely safer alternative that does not accomplish the denied action. +- **Plan before uncertain work:** If the task is not yet clear enough to safely execute, do not make small speculative edits. Continue read-only investigation or ask clarifying questions. When the work requires a shared plan before execution, enter plan mode (via ${ToolNames.ENTER_PLAN_MODE} if available, or the user's plan mode toggle) unless the user explicitly asked not to use plan mode. # Task Management diff --git a/packages/core/src/followup/speculationToolGate.test.ts b/packages/core/src/followup/speculationToolGate.test.ts index 502a3a41999..899a0a08fc2 100644 --- a/packages/core/src/followup/speculationToolGate.test.ts +++ b/packages/core/src/followup/speculationToolGate.test.ts @@ -149,6 +149,7 @@ describe('speculationToolGate', () => { ToolNames.MEMORY, ToolNames.ASK_USER_QUESTION, ToolNames.EXIT_PLAN_MODE, + ToolNames.ENTER_PLAN_MODE, ToolNames.WEB_FETCH, ])('hits boundary for %s', async (toolName) => { const result = await evaluateToolCall( diff --git a/packages/core/src/followup/speculationToolGate.ts b/packages/core/src/followup/speculationToolGate.ts index f3eae677950..6f531139301 100644 --- a/packages/core/src/followup/speculationToolGate.ts +++ b/packages/core/src/followup/speculationToolGate.ts @@ -48,6 +48,7 @@ const BOUNDARY_TOOLS = new Set([ ToolNames.MEMORY, ToolNames.ASK_USER_QUESTION, ToolNames.EXIT_PLAN_MODE, + ToolNames.ENTER_PLAN_MODE, ToolNames.WEB_FETCH, ]);
